Investigation of uncertainty in vibromonitoring of rotating systems transient modes

Earlier uncertainty investigation in vibration monitoring of rotating systems showed that uncertainty in stationary and periodic monitoring systems have different character. Uncertainty of stationary vibromonitoring systems of rotating systems have insignificant statistical component, while this uncertainty component plays main role while analyzing periodic vibration monitoring systems. This investigation expands the uncertainty analysis in stationary vibromonitoring systems adding transient mode. Uncertainty analysis is performed for different time and distribution intervals in order to determine whether statistical component of uncertainty still remains insignificant due to measurements quantity
